Without delay, let's solve this. We've got 652 and we will be multiplying it by 23, that is, adding 652 to itself 23 times.
Step 1: 0 + 652 = 652
Step 2: 652 + 652 = 1304
Step 3: 1304 + 652 = 1956
Step 4: 1956 + 652 = 2608
Step 5: 2608 + 652 = 3260
Step 6: 3260 + 652 = 3912
Step 7: 3912 + 652 = 4564
Step 8: 4564 + 652 = 5216
Step 9: 5216 + 652 = 5868
Step 10: 5868 + 652 = 6520
Step 11: 6520 + 652 = 7172
Step 12: 7172 + 652 = 7824
Step 13: 7824 + 652 = 8476
Step 14: 8476 + 652 = 9128
Step 15: 9128 + 652 = 9780
Step 16: 9780 + 652 = 10432
Step 17: 10432 + 652 = 11084
Step 18: 11084 + 652 = 11736
Step 19: 11736 + 652 = 12388
Step 20: 12388 + 652 = 13040
Step 21: 13040 + 652 = 13692
Step 22: 13692 + 652 = 14344
Step 23: 14344 + 652 = 14996

So, 652*23 = 14996
